We covered a lot in this chapter. We went from knowing nothing about Java syntax to learning about comments, variables, operators, and decision making.

As with any language, mastery of Java can be achieved by simply practicing, learning, and increasing our vocabulary. At this point, the temptation might be to hold back until mastery of the current Java syntax has been achieved, but the best way is to move on to new syntax at the same time as revisiting what we have already begun to learn.

In the next chapter, we will finally finish our math game by adding random questions of multiple difficulties as well as using more appropriate and random wrong answers for the multiple choice buttons.

To enable us to do this, we will first learn some more Java.
